Which of the following statements give characteristics of contact forces? 1. It appears between an object when it is in contact with some other object 2. It satisfies the third law of motion 3. It may appear between a pair of solid and fluid Select the answer using the code given below:

Correct option is D

The Correct answer is (d) 1, 2 and 3. Explanation: It appears between an object when it is in contact with some other object: This is correct. Contact forces arise when two objects physically touch each other. Examples include frictional forces, normal forces, and tension in ropes or springs. It satisfies the third law of motion: This is also correct. According to Newton’s Third Law of Motion, for every action, there is an equal and opposite reaction. Contact forces adhere to this law; for example, when you push on a wall, the wall pushes back with an equal and opposite force. It may appear between a pair of solid and fluid: This is also correct. Contact forces can occur between solids and fluids. For example, the buoyant force is a contact force exerted by a fluid on a solid object submerged in it, and drag is a contact force acting on an object moving through a fluid. Information Booster: Contact forces require physical contact between two objects, as opposed to non-contact forces like gravitational or electromagnetic forces. Friction, tension, normal forces, and air resistance are common examples of contact forces. In fluids, forces like buoyancy and viscous drag are contact forces that arise when a solid object interacts with the fluid.
